SPECIFICATION forming part of Letters Patent No. 577,164, dated February 16, 1897.

Application filed August l1, 1896. Serial No. 602,448. (No model.)

To all whom. it 71mg/ concern.:

13e it known that I, DANIEL W. HARPER, a citizen of the United States, residing at Birmingham,in the county of Jefferson and State of Alabama, have invented certain new and useful Improvements in Cash-Registers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, refer ence being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements in cash registers and recorders, and especially to an entirely new novel mechanical movement in this class of inventions whereby the recording` of a purchase is effected through the medium of a cog-wheel having broken series of teeth about its circumference,which teeth are cut at right angles to the axis of the wheel, each series of teeth designating a certain numerical amount corresponding to the amount of the purchase, and the said cog-wheel is regulated by mechanism which causes the teeth of the wheel to mesh with a pinion carried on a shaft connected with recording-wheels of any suitable construction common in the art, so that as an operating -sha'ft carrying the cog-wheel is pulled out the record of the purchase is made.

A further part of my invention resides in the provision of a shutter which is automatically operated so as to cover and obscure from view an indicating-numeral on a dial, or to be thrown back,disclosin g the purchase amount, the mechanism for operating which shutter being actuated each time that the shaft carrying the cog-wheel is pulled out in the act of recording a purchase.

In connection with the foregoing I provide means for rin gin g a bell each time that a purchase is made, and suitable mechanism for tilting the shutter backward and forward, which will be hcreinaf ter more fully described.

IIeretofore it has been the practice to construct recorders in connection with cash-reg isters in which a plurality of indicating-dials are utilized to record dollars and cents, while in the present invention I am able, by the peculiar and novel construction embodied in the mechanism which I em ploy, to utilize but one dial having both the cent and dollar numerals, and from which both denominations may be recorded by a pulling out of the same shaft.

To these ends and to such others as the invention may pertain, the same consists, further, in the novel construction, combination, and adaptation of the parts, as will be hereinafter more fully described, and then specifically defined in the appended claims.

I clearly illustrate my invention in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification, and in which drawings similar letters of reference indicate like parts throughout the several views, in which- Figure 1 is a central vertical section through my improved cash register and recorder. Fig. 2 is an end elevation with the face of the register removed. Fig. 3 is a top plan view of the interior mechanism with the shutter removed. Fig. 4 is a detail view of a perforated disk designed to hold the shaft from rotating while a purchase is being recorded. Fig. 5 is a side elevation of the dial on one end of the register together with the operating-handle and indicating-pointer. Fig. Gis an enlarged detail view of the mechanism which is designed to tilt the shutter. Fig. 7 is an enlarged detail in perspective of the shutter. Fig. S is a side elevation of the shutter.

Reference now being had to the details of the drawings by letter, A3 designates the cas ing of the cash-register, in which is carried at the bottom a money-drawer, and on the partition above the money-drawer are mounted the yokes B2 B2, in the perforated upper ends of which is carried the shaft S', to which is keyed or otherwise fastened the dial Q, having arranged upon opposite sides, if dedenominations, which in the present instance have numerals from O to $10. Mounted on the yoke I32 and in the front wall of .the register is the shaft S, which telescopes at one en d within the hollow shaft S', but is keyed so sired, the indicating-numerals of different IOO as to turn with the said shal't S. Keyed to the shaft S are the cog-wheels A and A', which have series ol broken teeth about their ci rcumferences, with smaller teeth in the broken cogs at right angles to the axes oi' the wheels. Meshing with the teeth ot the cog-wheel A is a pinion-wheel B, which is keyed to a sha't't having communication with the recordingwheels C, D, and E, which are of ordinar)T construction and connnonly used in the art. Hence no further detailed description et this part of the recordiiig mechanism is thought necessary. This wheel A is designed Yfor recording' any iL'iurehase the amountol.' which `is one dollar or below one dollar, while a second similariy-constructed cog-wheel A' is provided, which is designed to record purchases amounting' to dollars. A pinion L' is provided mounted on asuitable shaft carried on yolces, which pinion is designed to mesh with anyv series of cog-teeth on the wheel lt'which 'may be brought so as to mesh therewith. Suitable recording-wheels C', D', and lil are connected with this latter-relerred-to shaft, wherebtv the dollar purchases may be recorded.

On the front `l'ace ol' the register is a dial N, rigidly secured thereto, and the numerals on this dial are similarly arranged to those on the dial u, before relerred to.

An indicating-poni ter (f) is keyed to the shat't S on the outside ot' the register, and a row ot' integral lugs o' are disposed at intervals between the numerals on the said dial N. Keyed to the sha l`t S within the casing ot` the register is a disk l), which has a series ot conical-shaped apertures Z about its rim.

Secured to the inside wall oi the lront of the register is a conical-shaped member L', the vertical center ol which is coincident with a Vertical central plane throue'h the shaft interposed between the said disk 'L and the .liront wall et the register on the shal't S Yis a spring 3i, which normally holds the shal't in the position shown in Fig'. l of the drawings.

An angle-lever l), pivoied to a casi ing;7 has one end projecting' up in lront of the tace ot' the disk L and is retained in this position against the disk by means ol' the coiled spring' P', while the lower end ol. the said lever is hooked and designed to catch over a member 1"' to lock the drawer shut, and as the shaft S, carrying' the disk, is pulled out the lever tilts and the drawer is unlocked, as will be readily understood.

rthe number of teeth on the broken cog's correspoiulstotheninneralstrom l. i to l0 on the dials (t and N, and when it is desired to record a purchase the indieating-pointer o is turned with its shaft, which also turnsthe indieating-dial o, so that the amount ol' the purchase will appear at the indicating-aperture in the upright portion ot' the register. As the shaft S turns, the broken cog-wheel will also turn, so that the particular portion ot its surface which has a number ot teeth ing.

correspom'line; to tl t numeral. ol' the purchase comes so au to mesh with the pinion on the rcrordiug-shatt when `the shall` is pulled out to record the amount olf the purchase, and as the pinion is turned the recordine' el'leeted. As the disk li moves l'orward, the point et the member L' will engage with the conical aperture which in aliuement with said member, and which aperture is in the same plane with the numeral ou the indicating-dial, so that the disk will be steadily held .lrom turning' in either diret'- tion while the recording,r beine' done.

The shutter and mechanism tor opera tint: the same are as lol lows: lfivotta'l on suitable brackets X2 and X is the shutter7 made up ol the two pieces V l", connected logetlnfrat their upper ends and harina," thcirlower ends4 contracted and curved, as 'l'lest seen in liie'` 7 et 'the drawings. 'lhis shutter is piroled so as to straddle the dial H, and the strips connecting' the two plaies l' are t'lesigi'ned lo strike against the lever V'll'v and rino' the bell il" as the shutter tilts. t'ieeured about the circumference ot' the dial u is a series olf eros pieces Q" ot alengg'th slightlyloug'er than the distance between the plates hut ol.' surh a length as to readily pass lretwecu the sides ot 'the strips connecting the plates, and which strips, it willbe noted, are slie'litljt outwardtrlinclined as the;T 'rise upward. A second ss ries of lues t is i'lrorideffl, on opposite sides oli' the dial o., which are utilized iu connor-- tion with the lugrs or eross-pieces Q" l'or actuA ating'tl ishntter. 'lhecurvedlowcrporl ions` ol the shutter have 'the integral lugs lf, which, when the shutter is piroted in place. project Yin the path of the lugs Q' on the dial o.

'l'ournalcd in the brackets llt .is the rod lt, slit'linglyheld therein, and one end ot the said rod has the proiections lt, located a suitable distance apart, and one on each side olf the disk l), so that as the disk is mot'ed barkward and t'orward the said bar llt caused lo slide in the brackets supporting'- 'the same.

livoted in the bracket l." is 'the angle-lever T, one end ot which is engaged by a lient end t ol' lever l-t, while the other end resls normally above the arms ol the plates so that as the lever 'l' is tilted the shutter is caused to be tilted, so that the `upper wiiflened portion will swine' bark, exposing; the 'numeral ot' the purchase at the indiealine-openi lt will be noted that the dial n and the shutter are pirotcd on dil'l'erent centers, and that as the shutter is tilted bythe anejlederer 'l the upper end ol the wideuet'l plates l' will come within the path ot' the cresspieces Q" on the dialo, and that il. the dial is turned while the shutter is in its tilted position the cross-piece Q" which happens to be nett lo the shutter will bear against the edges ol.' the plates Y Y and cause the shutter to tilt back, so that the plates V will obscure the indicating-numeral opposite the aperture. -When the plates 'V ol. the sluittcr are turrnfd to a 'vertical position, the cross-piece which abuts against the plates V or an integral lug or lugs thereon will have reached such a position, the dial car 1ying the same being on a different center, that the cross-piece will be allowed to pass on uninterrupted and th e dial will be allowed to freely revolve without interference from the shutter.

It will be noted that when the shutter is in a closed position, covering the indicating-aperture, the integral point or lug U will be out of the path of the lugs Q and the dial may freely revolve in either direction, while when the shutter is in a tilted posit-ion and the dial CL is revolved to the right or in the direction of the movement of the hands of a clock the shutter will bc closed by a peg which contacts against the lug U, which projection U is in thc path of the lugs Q/ when the shutter is tilted. As the dial a, carrying the cross-pieces Q, moves to the right, the said cross-pieces Q will pass freely over the lugs on the plates Y at a point substantially half-way between the numerals as the lug Q is closing the shutter. So :it will be seen that whether the dial and its shaft are turned in either direction the shutter will be closed in case the latter is tilted back to expose the purchase amount.

In Ifig. 8 I have shown a modified form of shutter having two plates V on each arm thereof, which may be utilized in place of the shutter shown in Fig. 7, if preferred. In case the shutter shown in Fig. 8 is used one of the plates V will tilt back on each side of the indicating-apcrturc, and when the shutter is not tilted the indicating-aperture will disclose the purchase amount.

YWhat I claim to be new, and desire to secure by Letters Patent, is-
